SU66944A1 - A device for unloading logs, etc. long materials from carts or loading them on carts - Google Patents

Description

When unloading logs from wagons or when loading them onto wagons with ropes fixed at one end on the wagon, covering the log, enveloping blocks of racks installed on the side of the wagon, and wrapped by the second end on the drums of the winches, the ropes experience varying tension depending on their location.

In some positions, for example, when the supporting part of the rope is directed along the straight line connecting the attachment point to the rack unit, the pulling force required to lift the log increases greatly, and the ropes are subjected to very significant tensile forces.

In order to reduce the tension of the ropes and reduce the pulling force, on the uprights according to the invention, braces are mounted that carry the deflection blocks at the ends, which change the direction of the ropes, as a result of which the pulling force decreases, and with it the tension in the ropes.

In FIG. depicts the device used to unload logs from the gondola, and

FIG. 2 the same device used for loading logs in 1 gondola.

The device comprises two portable racks 2, installed along the gondola / at a distance corresponding to the length of the logs. The post 2 is attached to the rail 4 by means of a hook 5 connected to the post 2 by means of a tensioner b.

A hook 7 is mounted at the top of the rack, grabbing the gondola overboard. At the top of the racks reinforced blocks -5. Each rack is provided with a removable lance 9, having a slot at the lower end worn on a pin welded to the middle part of the rack, and at the upper end of the deflection block. The upper part of the strut is connected with the upper part of the rack 10.

The erected cable 12 is attached with one end to the side of the gondola, covers the lifted log, bends around blocks 8 and 11 and is wound with the second end on the winch drum 3. The lifted logs roll (Fig. 1) or ascend (Fig. 2) along the Inclined bar
